EUGENE W. THOMPSON, OF NE'W LONDON, CONNECTICUT.

HORSESHOE.

Application filed March 11, 1915.

T 0 all whom it may con ern:

Be it known that I, EUGENE V. T HOMP- SON, a citizen of the United States, residing at New London, in the county of New London and State of Connecticut, have invented a new and useful Horseshoe; and I do hereby declare the following to be a full clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved horseshoe, and it has for its object to provide improved means of securing the shoe calk in place.

Another object of the invention is to provide improved connections between the calks and the shoe whereby the calk may be easily attached and detached, so that the calk may be renewed when worn.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings, and claimed.

In the drawings:-

Figure 1 is a view in perspective of a horseshoe equipped with calks connected in place by the improved connections.

Fig. 2 is a sectional view on line 2-2 of Fig. 1, showing how the toe calk is secured.

Fig. 3 is a cross-sectional view through the toe calk on line 33 of Fig. 1.

Fig. 4 is a sectional view on line 44 of Fig. 1 showing how the heel calks are secured.

Fig. 5 is a cross-sectional view on line 55 of Fig. 1. showing the dovetail connection of the heel callv's.

Figs. (3 and 7 are detail views of the toe and heel calks showing their construct-ions before having been secured in place.

Referring more especially to the drawings, 1 designates a horseshoe of the usual shape and provided with the usual nail-receiving apertures 2 and the nail-head receiving grooves 3. The toe of the shoe adjacent its under surface is provided with a transverse dovtailed groove 4, to receive the elongated toe calk 5, which is V-shaped in crossscction to correspond with the shape of the groove 4. The end 6 of the toe calk is pro vided with an upwardly extending lug 7 of a Specification of Letters Patent.

shape to correspond with the curvature of the toe portion of the horseshoe, while the other end S of the toe calk is provided with a lug 9, wh ch normally extends in alinement with the toe calk, that is, before the calk is inserted in the groove. However, after the calk 5 is inserted. the lug 9 is bent upwardly, which, in cooperation with the lug 7, holds the calk 5 securely in place. These broad and heavy lugs 7 and 9 engage recesses 10 of the forward curvature of the toe portion of the shoe. It is to be noted that the opposite ends of the toe ca k extend beyond the forward curvature of the shoe, thereby providing a greater anti-slipping purchase on the ground. Said extensions are enabled to dig into the ice or sleet, there by preventing the shoe from slipping. It is to be observed that the dovetailed groove 4 is of a length substantially approximating the width of the heel of the shoe, so that the toe calk (which is of a length substantially the same as the width of the rear of the shoe) will have a firm bearing corr sponding to the bearing of the combined heel calks, thereby insuring a firm support for the foot of the animal. Furthermore, the extremities of the toe calk project beyond the marginal edge of the toe of the shoe, and overlie said toe, whereby the toe of the shoe adjacent the recesses 10 is protected against wear.

The heel extens ons 11 are provided with transverse dovetailed grooves 12. to receive the dovetailed heel calks 13. One end of each heel calk is provided with an upwardly extending lug 14 which engages a recess 15 of the outer edge of each extension 11. The other end of each heel calk is provided with a lug 16 ex ending normally in alinement with the calk. but after the calk is inserted in its dovetailed recess. the lug 16 is bent upwardly and into a recess 17 of the inner edge of each extension.

The invention having been set forth, what is claimed as new and useful is:-

A horseshoe having a dovetailed recess upon its under face and extending trans versely of the entire toe portion of the shoe, said dovetailed recess at its ends having auxiliary recesses in the marg nal edge of the toe of the shoe. said dovetailed recess being of a length substantially approximating the width of the heel of the shoe. a toe calk dovetailed in said dovetailed recess and being of a length substantially the same as the width of the rear of the shoe, whereby a firm bearing may be attained to correspond with the bearing of the combined heel calks, said toe calk overlying and projecting beyond the toe of the shoe, whereby the toe of the shoe adjacent the auxiliary recesses is protected against wear, the ends of the toe calk terminating in broadheavy up- 10 turned lugs engaging said auxiliary recesses,

thereby preventing endwise displacement of the toe calk.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses EUGENE W. THOMPSON.
